 1. Get to the OFW ok prompt, and reduce the volume of a XO-1.75 to zero
 using the keyboard.
  2. Power-off the XO, and power it on again.  Let it boot into Linux.
  3. Start TamTam or another activity which produces sound.  While the pop
 of the audio amplifier turning on can be heard, no output audio is
 produced.  Alsamixer does not show any volume controls abnormally set to
 zero or mute when this happens (compared to the OFW volume non-
 zero/working case).


 Seen with Q4D17 & 12.1.0 along with Q4D21 & 13.1.0 os5.
